【摘要】：理科教学中涉及很多抽象概念,学生无感性认识基础,在现有的认知发展水平上难以科学感知与建构这些概念。手持技术是一种先进的教育信息技术,能定量采集理科教学中的各种常见数据并呈现直观可视的曲线图像,将其作为认知工具有助于学生克服抽象概念学习中的认知难点。文章根据认知建构主义学习理论,从心理学角度分析学习者如何借助手持技术实验进行抽象概念学习,首次提出"多重转化、比较建构"认知模型,该模型认为手持技术支持下的概念学习是陌生概念到认知结构已有概念之间的转化,一般物质到具体物质之间的转化,定性认知到定量认知的转化,数据认知到图像认知的转化以及在比较参照中进行抽象概念建构等认知过程。并以"温室效应"概念学习为例,阐明该模型如何应用于教学实践,旨在丰富手持技术在概念认知领域的研究内容,并为教育信息化进程中科学有效开展基于手持技术的信息化概念教学提供参考依据。
[Abstract]:There are many abstract concepts involved in science teaching, students have no basis of perceptual cognition, and it is difficult to perceive and construct these concepts scientifically in the present level of cognitive development. Handheld technology is an advanced educational information technology. It can collect various kinds of common data in science teaching quantitatively and present visual curve images, which can be used as a cognitive tool to help students overcome the cognitive difficulties in abstract concept learning. Based on the cognitive constructivism learning theory, this paper analyzes how learners learn abstract concepts with the help of handheld technology experiments from the perspective of psychology, and puts forward for the first time a cognitive model of "multi-transformation, comparative construction". The model holds that concept learning supported by handheld technology is the transformation from unfamiliar concept to existing concept of cognitive structure, from general substance to concrete substance, from qualitative cognition to quantitative cognition. The cognitive process from data cognition to image cognition and abstract concept construction in comparative reference. Taking the concept learning of Greenhouse Effect as an example, this paper illustrates how the model can be applied to teaching practice in order to enrich the research content of handheld technology in the field of conceptual cognition. It also provides a reference for carrying out the concept teaching of informatization based on handheld technology in the process of educational informatization.
